Abstract

In the present invention, a toner supplying unit (130) includes a powder pump (131) and houses therein toner transferred by the powder pump (131). The powder pump (131) includes a stator (132) having a through hole (106) formed of a groove extending helically and a rotor (135) having a helical groove formed on the outer circumferential surface thereof such that a gap (G) for transferring the toner is formed between the helical groove and the inner circumferential surface of the through hole (106), and transfers the toner entering the gap (G) by rotating the rotor (135) and moving the gap (G). To the toner, inorganic fine particles with a volume-average particle diameter of equal to or larger than 30 nm are externally added.
